Abstract
The present invention provides a current collector, a battery including the current collector, which are capable of increasing energy density or output density and improving productivity or stability; it also provides a method for producing the current collector and a method for producing the battery. The current collector comprises: an insulating substrate; and electron-conducting portions respectively disposed on one face and the other face of the insulating substrate, at least two of the electron-conducting portions being disposed in a planar direction on the one face of the insulating substrate, the electron-conducting portions which is disposed on the other face of the insulating substrate being disposed in a manner to face at least one of the electron-conducting portions disposed on the one face of the insulating substrate so that the insulating substrate is interposed therebetween, and the electron-conducting portions disposed on the one face of the insulating substrate and the electron-conducting portions disposed on the other face of the insulating substrate, both of which face each other with the insulating substrate interposed therebetween, are connected to each other via electron conductors disposed in holes penetrating the insulating substrate.
